Unsymmetrical stibines of the type (C6H5)2Sb(CH2)nSb(C 6H5)2 show little or no asymmetry in the electric field gradient about the antimony nucleus. Large asymmetry is observed in cases where the diphenylstibino group is attached to Cl or is bound to an acetylenic linkage. This behavior is reminiscent of the occurrence of nuclear quadrupole splitting in tetravalent tin compounds and both phenomena may well arise from a common factor(s)-interaction of p electrons of the X group or polarity of the σ bonds. 121Sb Mossbauer spectra of trimethylstibine and the nqr spectra of (C6H5)2AsCH2As(C6H 5)2 and p-(C6H5)2AsCH2C6H 4CH2As(C6H5)2 have also been reported. The bond between As (or Sb) and the methylene group is electronically similar to that between As (or Sb) and the phenyl group.
